Studio work Through
IC4DESIGN, the illustration studio he founded and leads in
Hiroshima, Kamigaki has developed a sustained body of editorial, commercial, and narrative illustration work for both Japanese and international clients. The studio is recognized for its densely detailed, colorful cityscape imagery and narrative-rich compositions, and has maintained an international practice since the late 2000s while remaining headquartered in Hiroshima. Notable editorial projects include cover and feature illustrations for publications such as
The New York Times Magazine and
Los Angeles Times Magazine. Its commercial and institutional clients have included
Amtrak,
Adobe,
Newsweek,
Toyota,
Ogilvy, and campaigns for
UN Women, as well as digital projects such as
emoji design for
Google. The work produced through IC4DESIGN has been acknowledged through selection among the “200 Best Illustrators Worldwide” by BIS Publishers, inclusion in American Illustration and the
Society of Illustrators, and receipt of an
Art Directors Club of New York (ADC) Silver Award. Despite its global reach, Kamigaki has continued to maintain a strong professional presence in Hiroshima through regional commissions and collaborations.
Illustrated maze book series In parallel with commissioned work, Kamigaki and IC4DESIGN have produced the puzzle-book series
Pierre the Maze Detective, their most notable creation and a central element of the studio’s international recognition. The books feature double-page maze illustrations of bustling cityscapes, fantastical environments, and interconnected visual stories. The narrative follows Pierre and his companion Carmen as they pursue the thief Mr. X, whose magical artifacts transform ordinary settings into labyrinths. Since the publication of the first volume in 2014, the series has sold more than one million copies and has been translated into over thirty languages. The franchise has expanded to include activity books, merchandise, and a video-game adaptation released in 2021. The production of the first book of
Pierre the Maze Detective entailed the team moving from rough sketches to linework to final color across a workflow that took over two years to complete. Kamigaki has spoken frequently about how the Pierre series embodies his lifelong creative ambitions. His highly detailed style, shaped by exposure to international illustrators and by advice to create images viewers would study for “minutes, not seconds,” became a defining feature of the series. Kamigaki described the completed first book as feeling like his “personal art collection.” that contains “everything [he] ever wanted to draw.” The series has received international accolades for its detailed and highly interactive visual storytelling and graphic design, including being shortlisted for the World Illustration Awards from the
Association of Illustrators, receiving honors from the
ADC Awards, earning a NYX Awards Grand Winner distinction, and receiving honors at the Kyoto Global Design Awards.
Other activities and affiliations In addition to his illustration practice, Kamigaki has been active in broadcasting and education. He has worked as a radio personality and host on Hiroshima FM, reflecting his engagement with local media and the regional creative community. He has also led educational sessions at Anabuki Design College Hiroshima for graphic design students, contributing to professional training and mentorship in illustration and design. He served as a judge for the Illustration category of the 100th ADC Awards in 2021. Kamigaki has also taken on civic roles connected to his hometown. In 2024, he was appointed Kure Tourism Ambassador, receiving a formal letter of appointment from the mayor of Kure and speaking publicly about the city’s appeal, highlighting his ongoing involvement in local cultural promotion. ==Artistic style and technique==
